SULKY -PLOW.

SPECIFICATION forming part of Letters Patent no. 286,540, dated October9,1883.

Application filed April 14, 1883. (no model.)

To all whom it may concern Be it known that I, J our: 1. Hone, of SouthBend, in the State of Indiana, have invented certain new and usefulImprovements in Sulky- Flows; and I do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings, and to theletters of reference markedthereon, which form part of this specification, in which- Figure l is aside view of my improved means for operating the draft-tongue. Fig. 2 isan enlarged bottom view of the forward part of Fig. 1, showing thejointed tongue and the means for automatically locking and unlocking itby the draft of the team. Fig. 3 .is a perspective view for the purpose,of showing thebail or arched-axle support for the rear end of the plow,the lever for adjusting the same, and the device by which the. landsidewheel is adjusted. Fig. 4 is a perspective view in detail, showing howthe spring is applied to the bail or arched axle. Fig. 5 is aperspective view, showing how the spring-support for the draft-tongue isheld and adjusted. Fig. 6 is a perspective view of the device foradabout which the plow swings and by means of which the plow is flexiblyattached to the sullry-frameu Fig.8 is a diagram showing the diiferentpositions of lever X and .its slot,

ted. stub-axle slide in adjusting the landsidewheel.

This invention relates to novel improvements on archedaxle sulky-plows;and it consists in certain novel devices, which'will be fully understoodfrom the following description, when taken in connection with theannexed drawings. 4

I will here state that many of the devices and combinations of. deviceswhich Ishall herein describe and claim are improvements on LottersPatent which have been previously granted to me. The arched or bail axled is round in cross section, and to its left or landside end is bolted avertical guide, V, to which is applied the slide U, bearing thestub-axle f which slide, with its axle f is adjusted by means of anangular lever, X, turning about a pin, X, and throwing its wrist-pin Xforward and backwardin a slot, W, formed in the head of the slide U, asindicated inFig. 8. The slot W extends farther to the right of thevertical center of slide U than to its left, and the angular lever X ispivoted to the left of the vertical center of guideV. This arrangementof the parts causes the lever X to lift more vertically over the centerof the load, and enables this lever to lift through aspace equal totwice the length of the short arm ihereof, as indicated in Fig. 8. LeverX is held in position by a toothed segment and latch, in the usualmanner.

In this machine the plow is swung directly on the baiIZ by a broad loop,a, while the bail itself is connected to lever Y by a leafspring, T;(Shown in Figs. 3 and 4.) The lever Y turns loosely on the crank end ofthe said .bail. The spring T is rigidly attached to the bail and looselyto the leverbyaloop, t. The lever thus presses against spring T at t,which turns bail Z through its rigid connection therewith.

It is obvious thatthe support for the plow is a spring-support, enablingthe plow to run undisturbed by the vertical motions of the sulky, causedby the wheels passing over uneven ground. Lever Y is secured by atoothed segment and latch to frame 0, in the usual manner. The furrowside or arm of the axle d is bent slightly forward to carry its wheel onaxle-arm f clear of the earth as the. plow turns it. The U-shaped part 0of the sulkyframe and the axle d are connected by a wooden frame, K, tothe front end of which latter is bolted the jointed tongue, at D, andthe draft-tongue articulates vertically on bolt 1), and its motion inthis direction is limited by the flexibility of a leaf-spring, J, thefree end of which is held by an adjustable loop, L, secured to the frameor beam K, as shown in Figs. 1, 3, and 5.

Beneath loop L (see Fig. 3} is shown a footrest for the driver when onhis seat, and by. the side of this foot-rest I show an extension, M, ofthe tongue F, which serves as afootplowbeam by the'king-bolt or pin P.The

2 nseam 7 passed, by simply removing the foot from extension M thespring J will return the parts back to their normal positions. By meansof loop L the pitch or dip of the plow can be regulated and the plow setfor any kind of soil.

The jointed tongue G is hinged at H, and to its bottom side is fixed thedouble or heart shaped cam E. (Shown clearly in Fig. 2.) A

latch, 1), plays back and forth on the under side of section F of saidtongue. Through staples, and near the nose of the latch D", the end ofaconnectingrod, 0, passes through a hole in an offset shoulder, K. Therod 0 has a collar, 0 on it, by which it pushes latch D" into the notchof cam E when locking the tongue.

beam.

The said connecting-rod 0 extends backward and downward, and then, by asquare turn, its.

rear end passes under the front end of the plowbeam, and terminates inan eye, 0", through which draw-bar B slides freely. The extent of playgiven to the latch D is determined by the position of a nut, 0, which isadjustable forward or backward on the draw-bar B. The front end of thedraw-bar passes freely through a hole in the clevis S; By means of aslotthrough thisclevis (see Fig. 6) it can be adjusted up or down toregulate the direction of the draft. This clevis is bolted to the clipN, that is rigidly fixed to the front end of the plow- For clearness ofdescription, the clip N may be called the fixed part of the clevis, andS the adjustable piece through which the draft-rod passes. As the teamstarts, the draftrod B, by means of nut 0 and rod 0, throws the latchagainst the inclined side of heartcam E, and, as the team pulls, thetongue will be straightened and locked. Then the team stops pulling, thetongue is free to move either to the right or left, and the plow isdrawn around as in my patent above referred to.

It will be seen that by means of the adjustable finger b which isprovided with a setscrew, 1), and through which the long loop a passes,the plow can be held rigidly at one place on the bail Z,- or byloosening the setscrew b it can be allowed to swing free.

It is obvious from the above description that I have not only added to,but that I have taken from, the machine heretofore patented to medevices for the purpose of more fully and practically carrying out andperfecting my machine, and it will now be seen that I have a machinewhich is better arranged for the purpose of turning a sod with asulkyplow.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

adjustable loop, through which loop a passes freely, a plow-beam, avertically-adjustable bail, and a lever fixed to one of the cranked armsof this bail, and a spring, T, all constructed and adapted to operatesubstantially in the manner and for the purposes described.

4. The combination of the extensions of the U-shaped frame back of thearched axle, the vertically-movable bail, the plow suspended from thisbail, and laterally adjustable by means of along loop and slide, aleaf-spring, and a hand-lever connected thereto loosely, all constructedand adapted to operate substantially in the manner and for the purposesdescribed.

5. The combination of the bail Z, the frame 0, the hand-lever Y, thespring fast on the furrow end of the said bail, and the loop t, and thenotched segment and -catch, all constructed and adapted to operatesubstantially in the manner and for the purposes described.

6. The combination of the jointed tongue, the plow-beam, a draft-tongue,articulating vertically, a spring, J, an adjustable loop for Ithisspring, and the beam K, all arranged and adapted to operatesubstantially in the manner and for the purposes described.

7. The combination of the spring J the extension M, the tongue F, andthe loop L, all constructed and adapted to operate substantially in themannerand for the purposes described.
